Description
Technical field
This utility model relates to a kind of pathological tissue sampling instrument, especially a kind ofly shortens Diagnostic Time, reduces patient trauma and can improve pathological tissue thin slice harvester in the art of diagnostic accuracy.
Background technology
The pathological diagnosis at excision position be surgery especially the one of surgical oncology doctor in operation process and between clinical disease natural sciences promptly to hold a consultation mode, its objective is and make operative doctor determine next step art formula and the excision extension of pathological changes afflicted organ according to the pathological diagnosis (tissue is good pernicious) of censorship tissue, the waiting time therefore in art and the correctness of diagnosis are the two large keys determining that can successful surgery and patient fully recover.
The simplified process of current excision position pathological diagnosis is: surgeon excises a fritter or some pieces (multi-point sampling) representative tissue in lesion region, is sent to Pathology Deparment; Tissue to be dipped in liquid OCT embedding medium and to make it solidification under being placed in subzero 20 ~ 25 degrees celsius by pathologist, with freezing microtome, the organized OCT carrier of embedding is cut into slices again, then be pasted on after the tissue slice speed obtained being melted on microscope slide and carry out histopathology dyeing (i.e. HE dyeing) and microscopic examination, finally draw pathological diagnosis and inform operating room.Existing pathological diagnosis also exists following drawback:
1. pathological diagnosis process is loaded down with trivial details, and whole flow process at least needs 15 minutes, and 15 minutes for waiting for the doctor of diagnostic result in operating room and being in narcose patient longer;
2. the organizational structure after quick-freezing and speed are melted suffers destruction in various degree, good malignant cell in some cases tissue is not easily recognized, improve diagnosis difficulty, sometimes can only bear by having the expert enriching clinical pathology experience and just can draw diagnostic result after many people diagosis, not only require great effort, extend again the pathological diagnosis time simultaneously;
3. the existing stripping and slicing mode of drawing materials can cause comparatively macrolesion to diseased region, and when particularly needing multi-point sampling when avoiding mistaken diagnosis or need to determine focus edge (the different parts excision polylith tissue in focus), the damage brought is larger; Every block organization all needs embedding, freezing, section etc., makes the time of pathological diagnosis longer.
Summary of the invention
This utility model is the above-mentioned technical problem in order to solve existing for prior art, provides a kind of and shortens Diagnostic Time, reduces patient trauma and can improve pathological tissue thin slice harvester in the art of diagnostic accuracy.
Technical solution of the present utility model is: pathological tissue thin slice harvester in a kind of art, there are two breadloads, each breadload has front, back, bottom and upper segment, the front of each breadload is processed with front cutting edge, each breadload be processed with lower blade below, front cutting edge and lower blade are continuously and rounding off, described two breadloads vertically be arranged in parallel, the rear pad being positioned at the other front pad of front cutting edge and being positioned at rear side is provided with between two breadloads, the thickness of front pad and rear pad is equal, be 15 μm-30 μm, the lower end of described front pad is tangential on the arc that front cutting edge and lower blade rounding off are formed, the connector of connection two breadloads is provided with in the upper end of two breadloads or rear side.
The pathological tissue be in operation can directly be cut into slices by this utility model, obtains 15 μm-30 μm pathological tissue thin slices, can be fixed immediately and dye, carry out pathological diagnosis.Due to without the need to carrying out again embedding, freezing, section and freeze thawing treatment, not only simple to operate, and organizational structure is not destroyed, and the good malignant cell in tissue is easily recognized, save the pathological diagnosis time (at most only needing 10 minutes), improve the accuracy of diagnosis; Lamellar sampling process of the present utility model can to complete and wound is small instantaneously, no matter is that any is drawn materials or multi-point sampling, all can reduces the damage to patient to greatest extent.

Detailed description of the invention
Embodiment 1:
As shown in Figure 1, 2, 3: have two breadloads 1, breadload 1 can directly adopt the material of the adhesion organizations such as microscope slide to make.Each breadload 1 has front, back, bottom and upper segment, the front of each breadload 1 is processed with front cutting edge 2, each breadload 1 be processed with lower blade 3 below, front cutting edge 2 and lower blade 3 are continuously and rounding off, it is highly 1mm, and namely front cutting edge 2 forms arcuation with the connection transition position of lower blade 3; Two breadloads 1 vertically be arranged in parallel, are provided with the front pad 4 near front cutting edge 2 and the rear pad 5 being positioned at rear side between two breadloads 1.Rear pad 5 is relative front pad 4, and the object of setting is to balance with front pad 4, to ensure that two breadloads 1 vertically be arranged in parallel, also rear pad 5 can be placed in middle top position.The thickness of front pad 4 and rear pad 5 is equal, can select within the scope of 15 μm-30 μm as required, the lower end of described front pad 4 is tangential on the arc that front cutting edge 2 and lower blade 3 rounding off are formed, blade also can be processed in the lower end of front pad 4, is provided with the connector 6 of connection two breadloads 1 in the upper end of two breadloads 1.Connector 6 should ensure to fix up and down before and after two breadloads 1, can as shown in Figure 1 the fixture that two breadloads 1 are fixed as one.When breadload 1 is not when directly adopting microscope slide material, connector 6 can adopt the multiple connected mode such as hinge, bolt, after two breadloads 1 are used, relatively can open, be convenient to lamellar structure to take out.
Embodiment 2:
As shown in Figure 4,5:
Basic structure, with embodiment 1, with embodiment 1 difference is, rear pad 5 and connector 6 be by between two breadloads 1 processing groove and column realize.As processed groove on a breadload 1, the relative position of another breadload 1 processes to coincide with groove shape and height higher than the column of groove depth, during installation, column is inserted in groove, both parallel for guarantee two breadloads 1 and front and back upper-lower position can be fixed.
During use as shown in Figure 6, operative doctor can direct hand-held breadload 1, or is fixed on handle by breadload 1, and front pad 4, rear pad 5 connector 6 can ensure that breadload 1 is parallel to each other.First in lesion tissue, cut out lamellar with front cutting edge 2 and lower blade 3, gradually the back of breadload 1 is lifted again, cut lamellar can be separated with other positions of focus by the lower end of front pad 4, breadload 1 entirety is lifted, namely organizing of gathering be placed between two breadloads 1, and thickness is 20 μm.If what breadload 1 adopted is microscope slide, then directly carries out dyeing and microscopic examination without the need to taking out the pathological tissue thin slice gathered, finally drawing pathological diagnosis.Whole pathological diagnosis process at most only needs 10 minutes: cut and organize thin slice <1 second/sheet; Of short duration air-dry and be fixedly less than 30 seconds; Histopathology dyeing <5 minute; Microscopic examination <3 minute.
Use this utility model embodiment 1,2 successfully from rat main at the body organ (heart, liver, spleen, lung, kidney and skin) cut the tissue slice that thinness is 20 μm, as shown in Figure 7, prepared tissue slice structure keeps very intact, although tissue is slightly thick well arranged, is similar to the chipping qualities of paraffin-embedded tissue, therefore significantly reduce the difficulty of observation, reliable diagnosis can be made to pathological changes very soon.
